Activity of transaminase enzyme and testosterone hormone in blood of Awassi rams during different season

Abstract

Objective: To monitor the levels of aspartate transaminase (AST) and alanine transaminase (ALT) enzymes and testosterone hormone in months and seasons of Iraq. Methods: In this experiment, 20 (2.0-3.5 years old) Iraqi Awassi rams were used which were housed in semi opened shade. Blood samples (2-3 mL) were collected once a week for over period 12 mo. AST and ALT activities were measured by using colorimetric method, and testesterone analysis was performed with an automatic analyzer. Results: The activities of both AST and ALT enzymes were increased significantly (P
